I had an office with close to a thousand ports spread over a dozen VLANs waiting on a Juniper "expert" to configure routing / NAT / firewalling. Between hardware that was delivered non-functional, other hardware which wasn't properly licensed, and the lack of experience of this "expert", nothing was working for the first several days. In a fit of frustration, I asked for all VLANs to be sent to one port, then I set up a Raspberry Pi to do DNS and DHCP using a NetBSD host-based router to actually forward and do NAT. I told them it would stay that way until the Juniper gear was set up 100% and tested. They're excellent little machines, inexpensive, and wonderful to keep around "in case of emergency". Learn how to root off of a USB drive or to limit writes to the SD card, and they're wonderfully reliable, too.
